COMBINED LA'roH AND CONNECTOR Y one. Kubatiky, Stmuis, M0., assign@ toWin l Ventilator Company, St. Louis, Mo.,-a corpo'- f vration ofMissouri Appncation sapiente# so, 194e,y serial No. 700,309

f z emma (C1. zatrsi yThis,invention relates to fasteners and moreparticularly to a combined latch and minneetorv susceptible of. varioususes, such as to yieldably retain a door in a closed position oryieldalbly hold a plate or other device' in any of several predeterminedpositions, and to also retain a .plurality of elements in xed relationone to another, such as a handle to a door, or the flanges of anassembly in fixed relation.

The principal object of the invention is to pro vide a device of thischaracter which is inexpensive to manufacture, sturdy, easily installedand compact, avoiding the use of a plurality of screws,

bolts, rivets or the like for the purpose of securing thel latch inplace and fixedly connecting Atvro elements together.

A practical use for the combined latch and connector is fullyillustrated in my copending application for patent, for a window or wallventilator filed September 30, 1946, Serial No. 700,308, where thedevice is used to yieldably retain the swinging end shield of a -pivotedair deflecting or Ventilating shield in any one of many adjustedpositions, and to also xedly secure an architrave of the window to itsframe.

' Another practical use for the device is shown in the accompanyingdrawing, forming a part of this specification, wherein the device isassociated with the door of a metal cabinet, to yieldably retain thedoor in a closed position with respect to its jamb or architrave, and toalso xedly secure a handle to the door.

In the drawing: l

Fig. 1 is a plan view of the combined latch and connector.

Fig. 2 is a view in elevation of one side thereof.

Fig. 3 isa view in elevation of the other side particularly adapted forabutting relation with the element to which the device is secured.

Fig. 4 is a view in elevation of one end of the device.

Fig. 5 is a view in elevation of the other end and more particularly theend from which the bolt of the latch projects. n

Fig. 6 is a view partly in longitudinal section and partly in elevationon the line 6-6 of Fig. 2.

Fig. 7 is a fragmentary View in elevation showing a portion of a door, aportion of a jamb or architrave of a cabinet or the like, and a portionof a handle secured to the door by use of a combined latch and connectorof the character disclosed herein, the latter being shown mainly bydotted lines. Y

Fig. 8 is a View partly in section and partly in plan, on substantiallythe line 8-8 of Eig. 7.

Referring to the drawings, in'general the com binedlatch and connectorin 'accordance with my invention comprises a latch structure casing N,preferably an integral casting adapted to be secured to a closuremember.

shown 'in Figs. 7 and: 8 for example,- it maybe employed in connectionwith a first member II in juxtaposed 4relation to the casing, such as acab* inet door forcooperation with the-cabinet doork frame I2 andfunction as a connector element for securing a second member i3 injuxtaposed relation to lthe first member, "such as the door handle inits proper position on the door.

The latch Vstructure casing I0 as illustrated comprises an 'elongatedeasting'having aarlongitu-` dinal bolt housing bore I4 extendinginwardly from its front end and its rear end I5 reduced and providedwith a bolt, or rivet or like hole I6 extending therethrough.

The base I'I of the casting is flat for engagement with a casing orother structure except for lug projection I8 which extends suiciently toproject into two or more overlying aligning apertures, for example inthe first member II such as a sheet metal door and an aperture ordepression IB in the second member I3, such as in the base 20 of a doorAhandle as shown in Figs. 7 and 8. In this arrangement in place of anindividual ibolt, screw rivet or the like for securing the latch andconnector in place, the handle base 20 is provided with an integral lug2| constituting a threaded fastening means for extending through thebolt hole I6 of casing I0, this lug being threaded at its outer end forreceiving a nut 22. Thus the casing structure I0 is secured in place bymeans of a single fastening element, a bolt or the like, such as lug 2Iand nut 22 and this fastening and the lug I8 on the casing function tosecure both the connector and latch casing and the member I3 inpredetermined relationship with respect to the member II or likestructure such as heretofore referred to in my copending application.

The latch structure comprises a reciprocating bolt 23 in the form of aball with a compression spring 24 in the bolt housing bore I4 of casingI Il. These elements are secured against withdrawal from the bolt boreby means of a circumferential crimping 25 of the casing structureimmediately surrounding the outer end of bore Il! suficient to slightlyreduce the opening of the bore to prevent the removal of the bolt ball23 and also provide a seat therefor when it is in its normal fullyprojected position.

Thus the bolt ball 23 is yieldingly projected As fragmentarily'.

locked thereby in a definite relationship by means" of the projectingcasing lug I8 and a single fastening element, a screw threaded'bolt orlug 2| and nut 22. Having described a preferred and practical form ofcombined latch and connector in accordance with my invention it isobvious that 4in formit is subject to various changes within the scopeof my invention as defined in the following` claims.

I claim:

1. The combination cfa latch and iirst and se'cond membersY injuxtaposedrelation theretoand to each other, said rst and second`juxtaposed members provided with aligning apertures, said latchincluding a latch casing with a projectable latch therein, and a flatbase with anv extension froml an end thereof havinga hole therethrough,`alug projecting from the casing'base extending into said lapertures Ainboth ofV said juxtaposed members and fixing the positionof the latchcasing and said juxtaposed members with respect to each other, andthreaded fastening means extending through' thehole in 'the casing base'exi tension and cooperating withsaid first and secondV juxtaposedmembers for securing the latch' 3.@ 1,533,343*-v 4 and said members inthe position determined by said lug on the base of the latch casing.

2. A combined latch and connector comprising a latch structureconsisting of a latch casing open at its forward end for a projectablelatch member therein and a nat base, said casing being provided with anextension at one end thereof; said extension having 'a securing elementhole therein, a lug extending from said-latch casing base adjacent toone end thereof and adapted to extend through a corresponding hole in atleast one layer of sheet-material, a base element, said sheet materialbeing interposed between said base and said baseV element, and vsaidbase element having a securing member extending therefrom and throughthe sheet material and said securing element hole in said extension ofthe casing, and

said base element having an opening therein into which the lug on thebase extends, whereby the latch structure and securing member of saidbase elementcoact to secure the sheet material with respect to the latchstructure.
